nutrition and aging Flashcards
what chnages do we see in the mouth with age?
Xerostomia (dry mouht)
reduced smell and tatse
reduced power of chewing muscle
reduced pharyngeal phase of swallowing
Describe some of the structural changes in the mouth we may see with age
what can changes in the mouht as we age be a risk factor for?
anorexia of old age (unintentional weight loss)
Describe stomach related changes in aging
delayed gastric empyting
reduced gastric acid production
atrophic gastrisits
describe small intestine changes as we GE
Digestion and absorption of macros same
redu absoption in Ca, Zn, Vit D
commonly bacteria over growth can lead to decrease micronutrient absorption (Ca + Zn)
describe chnages in the large intestine as we age
Often slwoed motility and transit time that commonly lead to constipation
describe changes in the rectum as we age
redcued rectal wall elasticity
and increased wall threshold pressure
anus changes as we age?
reduced spincter pressure and reded anal squeeze pressure
describe changes in the pancreas as we age
describe changes to glucose tolerance as we age
degree of glucose intoelrance as we age - even in otherwise healthy people
every decade after 30 - increease in both postprandial and fasting glucose levels
how does skeletal muscle change as we age
there is an age related reduction in skeletal msucle mass causing dirutpion to the normakl rate of glucvose uptake
central to onset of diabetes
at 65% potentially lost 8-27% of msucle mass
what are postive factors that are protective against malnutriton in older adults
diet resillence (developing /adpating to maintain nutrient dense sufficient diet to meet requirements)
healthcare
socila support
exonomic health
what are negative factors that may predispose older perosn to be malnourished?
nutritonal frailty ( sudden signficant weight loss + loss of msucle mass + strneght or essential loss of physiological resevre)
age related sisease
cogntive issues
what is nutritional frailty
what is a food drug interaction
